<p>Comment (by Roland Haas):</p>
<p>I dug up the old meeting minutes from when LORENE2 was first introduced (from 2016):</p>
<p><a data-is-external-link="true" href="http://lists.einsteintoolkit.org/pipermail/users/2016-October/005020.html" rel="nofollow">http://lists.einsteintoolkit.org/pipermail/users/2016-October/005020.html</a></p>
<p>basically we introduced LORENE2 to indicate the breaking change and left LORENE as the default version in the thornlist.</p>
<p>At the very least we should be able to update LORENE2 to the current version (assuming no more breaking changes in between) and, if we want to deprecate LORENE1 and remove, possibly only in the release after the next one, switch defaults. The issue is that one cannot compile both thorns at the same time so switching from LORENE1 to LORENE2 will break existing parfiles (for example the gallery example).</p>
<p>Making LORENE2 the default was a decision reached in the ET call on 2018-03-12:</p>

<p>where it says:</p>
<p>--8<--<br />
updating LORENE:</p>
<ul>
<li>make LORENE2 the default after verifying that everything compiles and<br />
that gallery example works with LORENE2</li>
<li>check that BBH ID from Meudon group can still be read</li>
<li>create ticket for this</li>
<li>get this done within a month<br />
--8<--</li>
</ul>
<p>and from future minutes, nothing seems to have happened though in</p>
